Claims. .(Cl. 1014-391) The present invention relates to new and useful improvements in lock-up bars for split chases or forms used in printing tabloid newspapers or otherwise where it is desired to interchangeably pair one chase with another to avoid the time and labor of transferring the type from one chase to another.

When these forms or chases are locked up in the composing room they become sprung to a greater or lesser degree, causing a bow at their opposing edges where the two forms meet. Accordingly, it is an object of this invention .to provide a 1ock-up bar to compensate for the bowing or spring in the forms or chases.

An important object of the invention is to construct a lock-up bar for split chase equipped with lever means for rigidly clamping the bar to the pair of chases between the latter to maintain the same connected in spaced apart relation to each other.

Another object is to construct the lockup bar with a pair of resilient bars which conform to the bow or spring of the respective chase.

A further object is to provide a device of this character of simple and practical construction, which is efiicient and reliable in operation, easy to manipulate, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the detail of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view;

Figure 2 is a longitudinal sectional view taken on a line 2 2 of Figure l;

Figure 3 is a perspective view;

Figure 4 is an enlarged transverse sectional view taken on a line 4-4 of Figure 3;

Figure 5 is an enlarged longitudinal sectional view of one of the extensible links and taken on a line 5--5 of Figure 3; and

Figure 6 is a transverse sectional view taken on a line 6 6 of Figure 5.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numerals 5 and 6 designate a pair of chases or type forms which are locked to each other in side-by-side relation by the locking bar after the type has been locked in the chases in the usual manner. The locking of the type produces a bow as shown at 8 and 9 in the opposing edges of the chases and between which the locking bar designated generally at 10 is positioned.

The locking bar comprises a pair of resilient steel bars 11 and 12 which are connected to each other in spaced parallel relation by a T-shaped head 13 at one end of a pair of'bars which are bent outwardly as shown at 14 and 15 and riveted or otherwise suitably secured to the Aet , 2,7792 73 Patented Jan. 29, 1-957`V "ice y cross bar 16 at the head 13 and with the shank or stent 17 of the heal forming a spacer plate between the pair of bars and riveted thereto. A pair of pins 18 and 19 are welded or otherwise suitably secured to the ends 14 and 15 of the pair of bars and with the pins inserted in recesses 20 and 21 in the respective rear edges of the pair of chases.

A spacing `plate 22 is riveted or otherwise suitably secured between the front ends of the pair of bars 11 and12. y'

A sliding bead is shown'g'enerally at: 23'ar1d comprises a pair of angle iron members 24 and 25 connected to each other by a transverse guide pin 45 which is slidable in a longitudinal slot 46 in the locking bar 10 to slidably support the members 24 and 25 outside of the respective bars 11 and 12. The members 24 and 25 are provided with pins 26 and 27 adapted for entering recesses 28 and 29 in the front edge of the respective chase. A handle or lever 30 of channel shape includes a pair of anges 31 and 32 which are pivoted adjacent their inner ends to the pair of bars 11 and 12 by a transverse pin 33 and the inner ends of the flanges are pivoted to extensible links 35 and 36 by pins 37 and 38.

Each link comprises a pair of telesc-opically connected hollow cylindrical sections 39 and 40 having a coil spring 41 placed inside the sections to urge the same outwardly and abutting stops or anges 42 and 43|` on the inner ends of the sections limit relative outward movement thereof. The outer end of sections 39 of the links are pivoted to an adjacent member 24 or 25 of the sliding head 24 by a transverse pin 44 which is also slidable in the slot 46, while the outer end of section 40 is pivoted to the handle or lever.

The handle 30 is raised, as shown by dotted lines in Figure 2, to retract the pins 26 and 27 of the sliding head members 24 and 25 and after the pins of the heads 13 and 23 are placed in the recesses at the front and rear edges of the pair of chases 5 and 6, the handle 30 is lowered past center of the pivot of the handle, as shown by full lines in Figure 2, to place spring 41 of links 35 and 36 under tension and lock the chases in side-by-side relation to each other.

The resilient bars 11 and 12 ex to conform to the bows of the chases.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de scribed, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

l. A chase lock-up bar for a pair of chases comprising an elongated structure positioned between the meeting edges of the chases, a xed head connected to one end of the elongated structure, a slidable head carried at the other end of the elongated structure, means carried by said heads lockably connecting the same to the pair of chases, and manually actuated means carried by the elongated structure for locking the slidable head with the chases.

2. A chase lock-up bar for a pair of chases comprising a pair of bars positioned between the meeting edges of the chases, a fixed head connected to one end of the pair of bars, a slidable head carried at the other end of the pairs of bars, said chases having recesses therein, pins carried by said heads and received in said recesses, and manually actuated means carried by the pair of bars for locking the slidable head with the chases.

3. A chase lock-up bar for a pair of chases comprising pair of bars positioned between the meeting edges of y the chases a xed head connected to one end of the pair of bars, a slidable head carried at'the other end of the pair of bars, said chases having `recesses therein, pins carried by said heads andA received. in s'aid recesses, and alevver pivot/'ed to th-pairbf bars and 'coiiic "d to the "slidable ljea'd for at'ating the latter in a locking nove mm with@ chaises: s

5. In a chase lock-up bar for split chases having b'o'wd opposing side edges and said chases haying recesses in their front and rear edges, a pair of resilient bars, spacing members between the bars "at their vend portions spacing the bars in parallel relation to each other, said resilient bars being positioned between the chases to conform to the bow thereof, a stationary head at one end of the pair of bars and including pins engaged in the recess at the rear of the chases, a slidable head carried by the pair of bars at their otherends and including pins engaged in the recesses of the front Yof the chases, and manually actuating means for the slidable head and locking the latter in clamping position with the chases.
